TPS61041QDBVRQ1

Overview

The TPS61041QDBVRQ1 is an automotive-grade low-power DC-DC boost converter manufactured by Texas Instruments. It operates with a minimum input voltage of 1.8V and a maximum input voltage of 6V, providing a single adjustable output ranging from 1.8V to 28V. The device delivers a maximum output current of 250mA and supports a switching frequency between 50kHz and 1MHz. It is housed in a SOT-23-5 package and is qualified to AEC-Q100 standards for operation across a junction temperature range of -40°C to 125°C.

Feature Summary

• Automotive-grade reliability certified under AEC-Q100 standards
• Dedicated topology for small to medium LCD bias supply applications
• Optimized design for white LED backlight power requirements
• Compact surface-mount packaging suitable for space-constrained designs

Applications

• LCD bias supply circuits
• White LED backlight drivers
• Automotive electronic systems
• Low power DC/DC conversion modules

Procurement Notes

Verify the specific suffix QDBVRQ1 matches the required automotive qualification and package type. Confirm that the SOT-23-5 footprint aligns with the PCB layout constraints. Ensure the supplier provides valid traceability documentation for AEC-Q100 compliance. Check for any recent PCN updates regarding marking or assembly sources before finalizing orders.

Selection Notes

Select this component when designing for automotive environments requiring a compact boost solution. It is suitable for applications needing input voltages starting at 1.8V up to 6V. The fixed 250mA output current limits suitability for high-power loads. Consider the 50kHz to 1MHz frequency range for EMI management in sensitive automotive circuits.

Part Context

This part belongs to the TPS6104x series, which includes variants like the TPS61040-Q1. These devices are engineered specifically for low-power boosting tasks. The family focuses on efficiency and size reduction for portable and automotive electronics. The Q1 suffix indicates automotive grade qualification distinct from standard industrial versions.
